BRAKnnANenn MECHANISM.

Application filed April 12, 1923. "Serial m. 631,514.

To. all whom it may concern:

Be it known that I, Fnnnnnro II; BnNnnn,

a citizen of the UnitedStates, 'residing at Chicago, in the county of Cook and Stateoi Illinois, have invented certain new'and use ful Improvements in Brake-Hanger Mechanism, of which the following is a specification. r

This invention relates to brake hanger mechanism, 7 V

In the application of brake hangers to their supports, among other things, it is essential to consider proper clearance to accommodate movements of the brakes when the brake shoe and wheels are new and when worn, and also to consider the safety with which the brake hanger is held byits support: to prevent falling of the brake mechanism and possible wrecking of a train, and

at the same time consider the rapidity with I V which parts may be assembled and disassembled.

One object of the invention is to provide simple, novel and efficient means for securely supporting brake hangers to meet the requirements above mentioned. 7 7

- Another object is to provide a simple brake hanger arrangement in which the parts are interlocked in a manner-which insures safety in addition to a rapid assembly and disassembly of the parts, and in general adapted to meet the various requirements for successful use under service conditions.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheet of drawings, in which Figure 1 is a transverse sectional view through a side frame showing a brake hanger bracket and means for securing the brake hanger therein; a Figure 2 is a bottom plan rangement shown in Figure 1; and

"Figure 3 is a sectional view taken in the plane of line 3-3of Figure 1. v p

The various novel features of the invention will be apparent from the following de scription and drawings and will be particularly pointed out in'the appended claims.

Referring to the figures of the drawings, it will be noted that the invention is illustrated'in connection with a side frame having an integrally formedbracketll having a transverse opening 12 which is partially closed at the underside by two lips 13 view of the ary and 14L which extend toward each other and no r This key is provided with a semi-cylind'rical groove 16 in its upper surface for there ception of the upper horizontal portion 17 of a brake hanger having downwardly extending arms 18 which are located on either side of the key and which, when the brake hanger'is in normal operativeposition, em-

brace opposite sides of the lip 13 to prevent lateral displacement of the hanger and also to prevent lateral displacement of the key with respect to the bracket 11. In other words, while the key 15 looks the hanger against downward displacement, the hanger in cooperating with the bracket prevents displacement of the key; It will be" appreciated, of course, that the hanger is swung inwardly into the position shown in dotted lines in'Figure 3, when it and the key 15 areapplied to or withdrawn from the bracket. The upper wall of the opening 12 also has a semi-cylindrical portion for receiving the upper half of the upper l1orizontal portion 17 of the brake hanger so that the latter is embraced both by thebracket portion and by the removable key.

As the greater part of the wear due to the weight of supported parts is downward, such wear comes on key 15, but this key can be replaced at relatively small expense. The other parts of the bracketor means for sup porting the hanger are subject to little or no wear. Furthermore, with this arrangement it is impossible to forget to insert the locking element, for in this case thelocking element is the key 15 which also supports the brake hanger.

It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claims.

I claimi e 1. In brake mechanism, the combination of a key supporting member having an'undercurved lip, a key movably mounted on said member, and a brake hanger carried by said key, said brake hanger and lip having interengaging portions to prevent accidental displacement of said key,

2. In brake mechanism, the combination of a key supporting member including an undcrcurved lip, a key supported by said lip, and a brake hanger carried by said key. 3.7 In brake mechanism, the combination of a key supporting member including lips, a key supported by said lips, and a brake hanger carried by said key, one of said lips and hanger having interengaging portions for locking said'key in a given position.

4. In brake mechanism, the combination of a key supporting member having lips extending toward each other, a key supported by said lips, and a brake hanger carried by said key, said brake hanger and key being placed within saidv lips when the brake hanger is in a given position, one of-said lips and said hanger cooperating to prevent displacement of the latter and said key when mounted in said member, and a brake hanger carried by said key, said key and hanger being applied. to, said key supporting member when said hanger is in a given position, said member and hanger having interengaging parts for preventing accidentaldisplacement ofsa id key and hanger when the latter is in another position.
